My prediction holds that a lot of abilities after the patch will still be useless. They did numerous buffs to certain abilities, but did not address core mechanics besides the Witch Doctor mana change, which is definitely a correct decision. It is sad to see, however, that Monks will have largely the same spirit regeneration as before. The new set bonuses on items are also not too appealing.

Who will benefit the most from the patch? Just judging by the datamined notes, it will be:

Barbarian

Wizard

Demon Hunter

Witch Doctor

Monk

The Barbarian is going to absolutely stomp Inferno, and the Wizard has numerous new tricks up their sleeves. Demon Hunters got some well-rounded buffs, Witch Doctors will have many new playstyles, but Monks will mostly play the same as they do now.
